Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a wireless indicator testing system, a detection device, a testing method and equipment. Background Art

[0002] Wireless communication devices such as base station equipment, mobile phones, and tablet computers usually need to be tested for their RF indicators and other performance after leaving the factory. Currently, the testing process generally requires the use of a RF shielding box (also called a RF coupling box) and control equipment.

[0003] Currently, the RF coupling boxes on the market are all structures of passive antennas and shielding boxes. During testing, the device under test is placed in the shielding box to communicate with the passive antenna set in the shielding box. The test instrument is connected to the passive antenna. The test instrument tests the RF indicators of the device under test by analyzing the signal's transmission power and receiving power.

[0004] However, in this test method, there is an insertion loss (usually greater than 10dB) between the device under test and the test instrument, which has a great impact on the accuracy and stability of the test. Therefore, it is usually necessary to compensate for the insertion loss during the test. However, compensating for the insertion loss will increase the instrument's background noise, causing some indicators to be frequently mismeasured or even unable to be tested.

In the embodiment of the present application, a motor is arranged in the shielding box, and the motor drives the rotation of the antenna to find the angle of the antenna that minimizes the insertion loss. Then, when the antenna is at the angle that minimizes the insertion loss, the wireless indicators of the device under test are tested, thereby improving the accuracy of the test.

[0137] (3) Time domain indicators, such as sounding reference signals time mask (SRSTimeMask), physical random access channel (physical random access channel time mask, PRACHTimeMask), etc.

[0138] 2. Receive indicators.

[0139] For example, such as reference sensitivity (ReferenceSensitivityLevel) and the like.

[0140] The physical layer rate, also known as the throughput rate, can include the downlink throughput rates of 4G, 5G, and WIFI. The physical layer rate test of 4G can include LTE SingleBand and LTE CA tests, and the physical layer rate test of 5G can include NR SA, NR CA, and NR NSA throughput tests. The physical layer rate test of WIFI can be the indicators specified by standards such as 802.11n 11ac 11ax, etc.

[0141] In addition, the RF coupling box with single antenna coupling usually only supports single antenna testing, which can test RF indicators, but cannot test the physical layer rate of multiple input multiple output (MIMO). Although the air interface rate test can be performed by using multiple probes in a darkroom, the darkroom is heavy and large in size. Due to its large size and large path loss, high-power amplifiers need to be configured on the uplink and downlink respectively, so it has a high cost.

[0142] The embodiment of the present application also sets multiple antennas in the shielding box, for example, 4 linearly polarized directional antennas, and configures a motor for each antenna so that each antenna can rotate. When each antenna is at an angle that minimizes (or is smaller than) the insertion loss, the physical layer rate of the device under test is tested. This method enables the same RF coupling box to test both RF indicators and physical layer rates, and the test is performed when the insertion loss is small, making the test more accurate.

[0143] In addition, the size of the shielding box in the embodiment of the present application is relatively small, for example, it can be set to 60*60*80cm. Therefore, the manufacturing materials, such as wave absorbing materials and / or wave transparent materials, are saved, so that the weight of the shielding box is relatively small. Therefore, the construction cost of the shielding box is saved.

[0144] Furthermore, the embodiment of the present application also compensates for the insertion loss by providing a circuit board including a variable gain amplifier. The compensated insertion loss is minimum or less than a threshold value, and the threshold value is set by an external device, for example, the threshold value is 0dB, -1dB, 1dB. After compensating for the insertion loss, the wireless index test is performed on the device to be tested to improve the test accuracy.

[0145] like Figure 1 Shown is a schematic diagram of the architecture of a wireless indicator testing system provided in an embodiment of the present application.

[0146] The system includes but is not limited to a control device 1, a comprehensive tester 2, a detection device 3 and a device to be tested 5. The control device 1 is communicatively connected to the comprehensive tester 2. The antennas in the comprehensive tester 2 and the detection device 3 are electrically connected.

[0147] The control device 1 may be a computing device such as a mobile phone, a tablet computer, a laptop computer, or a PDA.

[0148] The device to be tested 5 may include one or more of a portable device, a desktop device and a wearable device. Portable devices include mobile phones, tablet computers, laptop computers and PDAs. Desktop devices include desktop computers, televisions, routers and printers. Wearable devices include bracelets, virtual reality (VR) glasses, augmented reality (AR) glasses, mixed reality (MR) glasses, Bluetooth headsets and wearable speakers.

[0149] The detection device 3 includes a shielding box 31, a plurality of antennas arranged in the shielding box 31, and a driving device, wherein the driving device may include one or more motors. Exemplarily, antenna A0, antenna A1, antenna A2, antenna A3 and antenna A4 are arranged in the shielding box 31, and these antennas are fixed on a turntable 32 in the shielding box 31, and the driving device includes motor M0, motor M1, motor M2, motor M3 and motor M4. Among them, motor M0 is used to drive the turntable 32 to rotate, and the turntable 32 drives the antennas A1-A4 to rotate to change the azimuth angle of the antennas A1-A4. Motors M1-M4 respectively drive the corresponding antennas A1-A4 to rotate to change the pitch angle of the corresponding antenna. Antenna A0 is an uplink antenna, which is used to provide an uplink with the device 5 to be tested. Antennas A1-A4 are downlink antennas, which are used to provide a downlink with the device 5 to be tested. The specific structure of the detection device 3 can be found in the following Figure 3A Related description in .

[0150] The full name of the comprehensive tester 2 is the wireless communication comprehensive tester. It can be used for various RF index tests or physical layer rate tests in different frequency bands, and is used in all stages of product development, production and maintenance. For example, the comprehensive tester CMW500 supports terminal tests of various communication standards, such as global system for mobile communication (GSM) test, general packet radio service (GPRS) test, global positioning system (GPS) test, wireless local area network (WLAN) test and application layer throughput test. The comprehensive tester has a built-in fading simulator that can simulate actual propagation conditions and perform tests.

[0151] The comprehensive tester 2 includes one or more output terminals and one or more input terminals. Exemplarily, the comprehensive tester 2 includes an input terminal IN and four output terminals, namely OUT1, OUT2, OUT3 and OUT4. Antenna 0 is connected to the input terminal IN, antenna A1 is connected to the output terminal OUT1, antenna A2 is connected to the output terminal OUT2, antenna A3 is connected to the output terminal OUT4, and antenna A4 is connected to the output terminal OUT4. The connection can be a direct connection or an indirect connection, wherein the direct connection is connected through a communication line, and the indirect link can be connected through a circuit, a device, etc.

[0152] In some embodiments, the comprehensive tester 2 includes a serial port (also called a COM port) and three output ports, namely OUT2, OUT3 and OUT4. The COM port of the comprehensive tester can be divided into an output port OUT1 and an input port IN by a one-to-two power splitter. The power splitter can be arranged inside the comprehensive tester 2 or outside the comprehensive tester 2.

[0153] When testing the radio frequency index, the antenna A0 and the antenna A1 in the detection device 3 only need to be connected to the COM terminal of the comprehensive tester 2 .

[0154] When testing the physical layer rate, the antenna in the detection device 3 is not only connected to the COM terminal of the comprehensive tester 2, but also connected to OUT2, OUT3 and OUT4. Among them, OUT1-OUT4 is used to provide downlink MIMO data stream when performing physical layer rate testing.

[0155] In the embodiment of the present application, the link through which the device under test 5 sends a signal to the comprehensive tester 2 is an uplink, and the link through which the comprehensive tester 2 sends a signal to the device under test 5 is a downlink. Exemplarily, the link through which the comprehensive tester 2 receives the signal sent by the device under test 5 through the antenna A0 is an uplink, also referred to as the uplink through the antenna A0. The link through which the comprehensive tester 2 sends a signal to the device under test 5 through the antenna A1 is a downlink, also referred to as the downlink through the antenna A1.

[0156] The control device 1 is used to control the motor M0 to drive the rotation of the antenna A1-A4 before testing the wireless index of the device under test 5, so as to change the azimuth angle of the antenna A1-A4. The control device 1 is also used to control the motors M1-M4 to respectively drive the rotation of one or more of the antennas A1-A4, so as to change the pitch angle of one or more of the antennas A1-A4. The control device 1 is also used to find the angle (i.e., target angle, optimal angle) of the antenna A1-A4 that minimizes the insertion loss of the downlink or makes the insertion loss of the downlink less than the threshold when controlling the motors M0-M4 to drive the antenna A1-A4 to rotate, that is, to make the maximum radiation direction of the antenna A1-A4 align with the angle of the receiving antenna of the device under test 5. Furthermore, the comprehensive tester 2 measures the wireless index when the antennas A1-A4 are located at the respective target angles, so as to reduce the influence of the insertion loss on the measurement accuracy and improve the measurement accuracy.

[0157] The threshold may be 2 dB, 5 dB, 10 dB, etc. The thresholds corresponding to different antennas may be the same or different.

[0158] Furthermore, compensation can be performed based on the insertion loss of antennas A1-A4 when they are located at target angles. The compensation method may include but is not limited to software compensation and hardware compensation.

[0159] The software compensation method can be: the control device 1 sends the insertion loss of antennas A1-A4 when they are respectively located at the target angle to the comprehensive tester 2. When the comprehensive tester 2 performs wireless index measurement, it can compensate the insertion loss of the uplink through antenna A0 and the downlink through antennas A1-A4 based on the received insertion loss. For specific implementation, please refer to the following Figure 5B The method embodiment shown is described in detail.

[0160] The hardware compensation method can be found in Figure 2 A schematic diagram of the architecture of a system for testing wireless indicators is shown.

[0161] The system includes the above Figure 1 In addition to the control device 1, the comprehensive tester 2, the detection device 3 and the device to be tested 5, the circuit board 4 is also included. The control device 1 is connected to the comprehensive tester 2 for communication. The comprehensive tester 2 is connected to the detection device 3. The circuit board 4 is connected between the comprehensive tester 2 and the detection device 3.

[0162] Circuit board 4 is also called a path gain control matrix, which is used to connect the comprehensive tester 2 and antennas A0-A4, adjust the gains of the paths where the comprehensive tester 2 and antennas A0-A4 are located, and compensate for the insertion losses of the uplink through antenna A0 and the downlink through antennas A1-A4, so as to provide a suitable signal level for the downlink.

[0163] The specific implementation of the circuit board 4 can refer to the following Figure 4A or Figure 4B The circuit board shown will not be described in detail here.

[0164] Specifically, the control device 1 controls the circuit board 4 to compensate for the insertion loss based on the insertion loss when the antennas A1-A4 are respectively located at the found angles. Figure 5A The method embodiment shown is described in detail.

[0165] Combine as follows Figure 3A A structural example diagram of a detection device 3 provided in an embodiment of the present application is introduced.

[0166] The detection device 3 includes but is not limited to a shielding box 31, one or more antennas, a driving device and a turntable 32. The shielding box 31 includes a wave-transmitting plate 311 and an absorbing material 312 arranged on the inner wall of the shielding box 31. The wave-transmitting plate 311 is used to support the device under test 5. The absorbing material 312 is located on the first side of the wave-transmitting plate 311. During the test, the device under test 5 is located in the space formed by the wave-transmitting plate 311 and the absorbing material 312. One or more antennas are arranged on the surface of the turntable 32 opposite to the second side of the wave-transmitting plate 311. The first side and the second side of the wave-transmitting plate 311 are opposite sides of the wave-transmitting plate 311. The driving device may include one or more motors.

[0167] The shielding box 31 can be a plastic shell. Based on the different devices under test 5, the size of the shielding box 31 can be different. The size of the shielding box 31 can be expressed as a*b*c, where a represents the length of the shielding box 31, b represents the length of the shielding box 31, and c represents the length of the shielding box 31. Wherein, a is 20cm-100cm, b is 15cm-100cm, and c is 5cm-100cm. Exemplarily, the device under test 5 is a mobile phone, and the size of the shielding box 31 can be 30cm*30cm*13cm or 60cm*60cm*80cm. It should be understood that the shielding box 31 can also be other sizes. The shielding box 31 can be divided into two parts, upper and lower.

[0168] The upper part is the anechoic test space, that is, the space formed by the wave-transmitting plate 311 and the wave-absorbing material 312, see Figure 3BThe top of the anechoic test space is openable, and is also called a door, for placing and taking out the device under test 5. The inner wall of the top and the inner walls around are covered with absorbing materials 312 for absorbing reflected electromagnetic waves to prevent the multipath effect from affecting the test results.

[0169] The upper and lower parts are separated by a wave-transparent plate 311 and used as a test platform for placing the device to be tested. The wave-transparent plate 311 can be a hard foam board, which has a small electromagnetic wave penetration loss while providing a certain support strength.

[0170] The lower part is a multi-axis multi-antenna servo system, see Figure 3C The multi-axis multi-antenna adjustment system shown is a top view. The multi-axis multi-antenna adjustment system includes a motor M0, a turntable 32 fixed on the rotating shaft of the electrode M0, an antenna A0 fixed at the central axis of the turntable 32, electrodes M1-M4 and antennas A1-A4 fixed on the turntable 32. Antenna A0 serves as an uplink antenna, and the four antennas (i.e., A1-A4) serve as downlink antennas. The bottom edges of antennas A1-A4 are respectively fixed on the rotating shafts of the four motors M1-M4, and the motors M1-M4 are respectively used to drive antennas A1-A4 to adjust the pitch angles of antennas A1-A4 to ensure that the maximum radiation direction of antennas A1-A4 is aligned with the receiving antenna of the device under test. Antenna A0 is placed at the center of the turntable to receive the uplink signal of the device under test 5. Antennas A1-A4 are used to transmit downlink signals to the device under test 5.

[0171] In one implementation, Figure 3A As shown, the turntable 32 can rotate 360° around the vertical center axis. At this time, the turntable 32 is fixed on the rotating shaft of the motor M0, and the motor M0 is used to drive the turntable 32 to rotate. When the turntable 32 rotates, the antennas A1-A4 on the turntable 32 are driven to rotate to adjust the azimuth angles of the antennas A1-A4.

[0172] In addition, the above uses 5 antennas and 5 motors as an example, and it should be understood that the detection device 3 may include more or fewer antennas, more or fewer motors. Exemplarily, the detection device 3 may include 2 antennas (i.e., antenna A0 and antenna A1) and motors corresponding to the 2 antennas (i.e., motors M0 and M1), and the detection device 3 can be used to measure radio frequency indicators.

[0173] In some embodiments, antennas A0-A4 are all ultra-wideband antennas. For example, antenna A0 may be a circularly polarized directional antenna, and antennas A1-A4 may be linearly polarized directional antennas. Using circularly polarized directional antennas as uplink antennas can reduce the impact of the rotation of the turntable 32 on the level of the uplink signal.

[0174] The bandwidth of the linearly polarized directional antenna may be 0.7 to 6 GHz, and illustratively, its size is 11*16 cm.

[0175] Figure 3D The schematic diagram of the distribution of an antenna is shown as an example. Figure 3D As shown, the circular polarization directional antenna is antenna A0 disposed at the center of the surface of the turntable 32, and antenna A1 is distributed around antenna A0. The position relationship between antennas A0 and A1 is not limited to the above, and other position relationships may also be included.

[0176] In another antenna distribution method, the circularly polarized directional antenna, that is, antenna A0, is set at the center of the turntable 32, and four linearly polarized directional antennas (that is, antennas A1-A4) are distributed around antenna A0, and are centrally symmetrically distributed with respect to the geometric center of antenna A0. Figure 3C Another schematic diagram of antenna distribution is shown as an example. Figure 3C As shown, antennas A1-A4 are located at the midpoints of the four sides of the square, respectively, and antenna A0 is located at the geometric center of the square.

[0177] In the above Figure 3D and Figure 3C In the embodiment, antennas A1-A4 can rotate about the central axis of the turntable 32 (i.e., the axis perpendicular to the support surface provided by the turntable 32) to change their azimuth angles. The variable range of the azimuth angles of antennas A1-A4 can be 0°-360°. Antennas A1-A4 rotate about the axis parallel to the support surface provided by the turntable 32 to change their elevation angles. The variable range of the elevation angles can be 0°-45° or 0°-90°, etc. The elevation angle of an antenna is the angle between the extension direction of the antenna and the axis perpendicular to the support surface provided by the turntable 32. Figure 3E It is a side view of a part of the detection device 3 , which exemplarily shows the elevation angle of the antenna A1 and the rotation direction of the azimuth angle of the antenna A1 .

[0178] For example, in the above Figure 3D In the embodiment, the antenna A1 can also rotate on the supporting surface provided by the turntable 32. Figure 3F The rotation track of the antenna A1 is exemplarily shown to ensure that the maximum radiation direction of the antenna A1 is aligned with the receiving antenna of the device under test.

[0179] Optionally, the detection device 3 comprising one uplink antenna and four downlink antennas can be used to measure radio frequency indicators and physical layer rate. The detection device 3 comprising one uplink antenna and one downlink antenna can be used to measure radio frequency indicators.

[0180] Combine as follows Figure 4A and Figure 4C The following is a circuit diagram of two circuit boards provided in the embodiments of the present application.

[0181] The circuit board 4 includes but is not limited to one or more gain circuits, one or more direct circuits and one or more switch modules. Each gain circuit corresponds to each switch module, and each direct circuit corresponds to each switch module. The direct circuit refers to one end of the comprehensive tester connected to the antenna through a wire or directly connected, and the gain circuit refers to one end of the comprehensive tester connected to the antenna through a variable gain amplifier. The switch module is used to switch the connection mode between one end of the comprehensive tester and the antenna, that is, to switch between the direct circuit and the gain circuit.

[0182] Figure 4A The circuit board 4 is exemplarily shown to include a gain line L0, a gain line L1, a through line D0, a through line D1, a switch module S0 and a switch module S1. The gain line L0 includes a variable gain amplifier P0; the gain line L1 includes a variable gain amplifier P1. The through line D0, the gain line L0 and the switch module S0 are used to connect the antenna A0 and the input terminal IN of the comprehensive tester 2. The switch module S0 is used to switch the first connection mode and the second connection mode. The first connection mode is that the comprehensive tester 2 is connected to the antenna A0 through the through line D0. The second connection mode is that the comprehensive tester 2 is connected to the antenna A0 through the gain line L0. The through line D1, the gain line L1 and the switch module S1 are used to connect the antenna A1 and the OUT1 of the comprehensive tester 2. The switch module S1 is used to switch the third connection mode and the fourth connection mode. The third connection mode is that the comprehensive tester 2 is connected to the antenna A1 through the through line D1. The fourth connection mode is that the comprehensive tester 2 is connected to the antenna A1 through the gain line L1.

[0183] For example, Figure 4B As shown, the variable gain amplifiers P0 and P1 may include: a radio frequency gain block, a radio frequency equalizer, a programmable attenuator and a radio frequency power amplifier.

[0184] Among them, the RF gain block is used to provide the amplification gain of the previous stage circuit, while reducing the sensitivity of the cascade noise coefficient to the insertion loss of the subsequent stage circuit. The RF equalizer is used to adjust the unevenness of the gain, correct the unevenness exceeding the first preset value to the second preset value, and provide a relatively flat amplification factor for signals of different frequencies. Among them, the first preset value and the second preset value are preset. Exemplarily, the first preset value is 10dB and the second preset value is ±1dB. The programmable attenuator is used to indirectly adjust the gain of the entire variable gain amplifier by controlling the attenuation value. The RF power amplifier at the end is used to provide a stronger power output to avoid distortion when the signal input to the lower stage circuit is large, so as to improve the output capacity of the final stage circuit. It should be understood that if the output capacity is insufficient, the amplifier will saturate when the input signal is large, and enter the nonlinear region prematurely, resulting in distortion.

[0185] Specifically, for the variable gain amplifier P0, the input end of the RF gain block is connected to the antenna A0, and is used to amplify the uplink signal received through the antenna A0, etc. The output end of the RF gain block is connected to the input end of the RF equalizer, and the RF equalizer is used to adjust the unevenness of the gain of the input uplink signal. The output end of the RF equalizer is connected to the input end of the programmable attenuator, and the programmable attenuator is used to be controlled by the controlled device to adjust the gain of the entire variable gain amplifier based on the insertion loss of the uplink. The output end of the programmable attenuator is connected to the input end of the RF power amplifier. The output end of the RF power amplifier is connected to the IN of the comprehensive tester 2 to increase the power of the uplink signal input to the IN of the comprehensive tester 2.

[0186] For the variable gain amplifier P1, the input end of the RF gain block is connected to the OUT1 of the comprehensive tester, and is used to amplify and process the signal output by the OUT1 of the comprehensive tester. The output end of the RF gain block is connected to the input end of the RF equalizer, and the RF equalizer is used to adjust the unevenness of the gain of the input downlink signal. The output end of the RF equalizer is connected to the input end of the programmable attenuator, and the programmable attenuator is used to be controlled by the controlled device to adjust the gain of the entire variable gain amplifier P1 based on the insertion loss of the downlink through the antenna A1. The output end of the programmable attenuator is connected to the input end of the RF power amplifier. The output end of the RF power amplifier is connected to the antenna A1 to increase the power of the downlink signal transmitted through the antenna A1.

[0187] It should be noted that the RF equalizer and RF power amplifier are not necessary components of the variable gain amplifier. In another implementation, the variable gain amplifier may not include an equalizer, that is, the output of the RF gain block is directly connected to the input of the programmable attenuator.

[0188] Exemplarily, the switch module S0 includes four switches, namely switch S0-1, switch S0-2, switch S0-3 and switch S0-4. The switch module S1 includes four switches, namely switch S1-1, switch S1-2, switch S1-3 and switch S1-4.

[0189] The first end of switch S0-1 is connected to the input end IN of comprehensive tester 2, and the second end of switch S0-1 is connected to the output end of variable gain amplifier P0, that is, connected to the second end of RF power amplifier. The input end of variable gain amplifier P0 (that is, the first end of RF gain block) is connected to the first end of switch S0-2, and the second end of switch S0-2 is connected to antenna A0. The first end of switch S0-3 is connected to the input end IN of comprehensive tester 2, the second end of switch S0-3 is connected to the first end of switch S0-4, and the second end of switch S0-4 is connected to antenna A0. The first end of switch S1-1 is connected to OUT1 of comprehensive tester 2, and the second end of switch S1-1 is connected to the input end of variable gain amplifier P1, that is, connected to the first end of RF gain block. The output end of variable gain amplifier P1 (that is, the second end of RF power amplifier) ​​is connected to the first end of switch S1-2, and the second end of switch S1-2 is connected to antenna A1. A first end of the switch S1 - 3 is connected to OUT1 of the comprehensive tester 2 , a second end of the switch S1 - 3 is connected to a first end of the switch S1 - 4 , and a second end of the switch S1 - 4 is connected to the antenna A1 .

[0190] Switches S0-1 and S0-2 are turned on and off at the same time, switches S0-3 and S0-4 are turned on and off at the same time, and switches S0-1 and S0-2 are not turned on at the same time as switches S0-3 and S0-4. Similarly, switches S1-1 and S1-2 are turned on and off at the same time, switches S1-3 and S1-4 are turned on and off at the same time, and switches S1-1 and S1-2 are not turned on at the same time as switches S1-3 and S1-4.

[0191] The control ends of the switches in the switch module S0 and the switch module S1 are both connected to the control device 1. The control device 1 is used to control the on and off of the switches.

[0192] The switch module is not limited to including 4 switches, and in other embodiments, it may also include more or fewer switches.

[0193] Exemplarily, the switch module S0 only includes the switch S0 - 1 and the switch S0 - 3 . In this case, the input end of the variable gain amplifier P0 and the second end of the switch S0 - 3 are directly connected to the antenna A0 .

[0194] Exemplarily, the switch module S1 only includes a switch S1 - 1 and a switch S1 - 3. At this time, the output end of the variable gain amplifier P0 and the second end of the switch S1 - 3 are directly connected to the antenna A1.

[0195] Above Figure 4A Only one downlink compensation circuit is shown, that is, a circuit between an output terminal of the comprehensive tester 2 and a downlink antenna. In another embodiment, the circuit board may further include more downlink compensation circuits.

[0196] like Figure 4C As shown, Figure 4C The circuit diagram of another circuit board 4 is exemplarily shown. The circuit board 4 also includes a compensation circuit between OUT2 of the comprehensive tester 2 and the downlink antenna A2, a compensation circuit between OUT3 of the comprehensive tester 2 and the downlink antenna A3, and a compensation circuit between OUT4 of the comprehensive tester 2 and the downlink antenna A4.

[0197] The same compensation circuit between OUT1 of the comprehensive tester 2 and the downstream antenna A1 as the compensation circuit between OUT2 of the comprehensive tester 2 and the downstream antenna A2 includes a gain line L2, a direct line D2 and a switch module S2. Similarly, the compensation circuit between OUT3 of the comprehensive tester 2 and the downstream antenna A3 includes a gain line L3, a direct line D3 and a switch module S3. The compensation circuit between OUT4 of the comprehensive tester 2 and the downstream antenna A4 includes a gain line L4, a direct line D4 and a switch module S4. Among them, the gain line L2 includes a variable gain amplifier P2; the gain line L3 includes a variable gain amplifier P3; the gain line L4 includes a variable gain amplifier P4. Among them, the connection mode of the gain line L2-L4 refers to the connection mode of the above-mentioned gain line L1. The connection mode of the direct line D2-D4 refers to the connection mode of the above-mentioned gain line D1.

[0198] The switch module S2 is used to switch the connection mode between OUT2 of the comprehensive tester 2 and the antenna A2, the switch module S3 is used to switch the connection mode between OUT3 of the comprehensive tester 2 and the antenna A3, and the switch module S4 is used to switch the connection mode between OUT4 of the comprehensive tester 2 and the antenna A4. Like the above-mentioned switch module S2, the connection mode includes a third connection mode and a fourth connection mode. The third connection mode is that the comprehensive tester 2 is connected to the antenna through a direct line.

[0199] The switch modules S2-S4 may each include 4 switches. The connection method of the switches in the switch modules S2-S4 refers to the connection method of the switches in the above-mentioned switch module S1. Exemplarily, the switch module S2 includes switches S2-1, S2-2, S2-3 and S2-4. The first end of the switch S2-1 is connected to OUT2 of the comprehensive tester 2, and the second end of the switch S2-1 is connected to the input end of the variable gain amplifier P2, that is, connected to the first end of the RF gain block. The output end of the variable gain amplifier P2 (that is, the second end of the RF power amplifier) ​​is connected to the first end of the switch S2-2, and the second end of the switch S2-2 is connected to the antenna A2. The first end of the switch S2-3 is connected to OUT2 of the comprehensive tester 2, the second end of the switch S2-3 is connected to the first end of the switch S2-4, and the second end of the switch S2-4 is connected to the antenna A2.

[0200] It should be understood that the switch modules S2-S4 may include more or less than 4 switches. For example, the switch module S2 only includes switch S2-1 and switch S2-3.

[0201] It should also be understood that the number of switches in the switch modules S0 - S4 may be different.

[0202] The following is combined with the above Figure 1 , Figure 2 The system shown, Figure 3A The detection device shown and Figure 4A , Figure 4C The circuit board shown specifically describes the technical solutions for finding the angle with the minimum insertion loss and compensating for the insertion loss involved in the embodiments of the present application.

[0203] Find the target azimuth angle of antenna A1 that minimizes the insertion loss of the downlink through antenna A1:

[0204] The control device 1 is also used to control the motor M0 to rotate in steps of 2°, 5°, 10° or 15° to change the azimuth angle of the antenna A1 before testing the RF index or physical layer rate of the device under test. The smaller the step size, the more accurate the angle that minimizes the insertion loss, and the larger the step size, the faster the search speed. Each time it rotates, the comprehensive tester 2 needs to perform a measurement.

[0205] The control device 1 is used to send a first instruction to the comprehensive tester when the antenna A1 is located at an initial angle and after each rotation, and the first instruction is used to instruct the comprehensive tester to transmit a first signal through the antenna A1.

[0206] The comprehensive tester 2 is also used to respond to the first instruction, transmit a first signal with a first reference signal receiving power RSRP value through antenna A1; and receive a readback signal from the device under test 5 through antenna A0, the readback signal carrying a second RSRP value of the received first signal measured by the device under test.

[0207] The comprehensive tester 2 is further used to parse the second RSRP in the read-back signal, and send the first RSRP value and the second RSRP value to the control device 1 .

[0208] The control device 1 is also used to determine the insertion loss of the downlink through the antenna A1 based on the difference between the first RSRP value and the second RSRP value. Exemplarily, the difference between the first RSRP value and the second RSRP value is the insertion loss of the downlink. The control device 1 is also used to determine the minimum insertion loss of the downlink from the insertion loss calculated when the antenna A1 is at the initial angle and the insertion loss calculated each time the antenna A1 rotates, that is, the minimum insertion loss of the downlink through the antenna A1, and then determine the angle of the antenna A1 when the insertion loss is minimum as the target azimuth angle of the antenna A1.

[0209] In another implementation, the comprehensive tester 2 is further used to send the second RSRP value to the control device 1. The control device 1 is also used to determine the maximum second RSRP value from the second RSRP value when the antenna A1 is located at the initial angle and the second RSRP value received each time the antenna A1 rotates, because the insertion loss corresponding to the maximum second RSRP value is the minimum insertion loss of the downlink through the antenna A1, and thus, the antenna A1 angle corresponding to the maximum second RSRP value is the target azimuth angle of the antenna A1.

[0210] Optionally, the control device 1 is used to control the switch module S0 to switch to the second connection mode before sending the first instruction to the comprehensive tester 2, adjust the gain of the variable gain amplifier P0 to a preset value (such as 10dB), and control the switch module S1 to switch to the third connection mode. Specifically, the control device 1 is used to control the switch S1-1 and the switch S1-2 to be disconnected, and control the switch S1-3 and the switch S1-4 to be connected, that is, to switch to the third connection mode, so that in the third connection mode, the comprehensive tester 2 transmits the first signal with the first RSRP value through the antenna 1. The control device 1 is used to control the switch S0-1 and the switch S0-2 to be connected, and control the switch S0-3 and the switch S0-4 to be disconnected, that is, to control the switch module S0 to switch to the second connection mode, so that in the second connection mode, the comprehensive tester 2 receives the readback signal of the first signal from the device under test 5 through the antenna A0.

[0211] Find the target elevation angle of antenna A1 that minimizes the insertion loss of the downlink through antenna A1:

[0212] The control device 1 is used to control the motor M1 to rotate in steps of 2°, 5°, 10° or 15° to change the pitch angle of the antenna A1 before testing the RF index or physical layer rate of the device under test. The smaller the step size, the more accurate the target pitch angle is, and the larger the step size, the faster the search speed is. Each time it rotates, the comprehensive tester 2 needs to perform a measurement. Optionally, when the motor M1 is controlled to drive the antenna A1 to rotate, the azimuth angle of the antenna A1 is the target azimuth angle.

[0213] The control device 1 is used to send a first instruction to the comprehensive tester when the antenna A1 is located at an initial angle and after each rotation, and the first instruction is used to instruct the comprehensive tester to transmit a first signal through the antenna A1.

[0214] The comprehensive tester 2 is also used to respond to the first instruction, transmit a first signal with a first reference signal receiving power RSRP value through antenna A1; and receive a readback signal from the device under test 5 through antenna A0, the readback signal carrying a second RSRP value of the received first signal measured by the device under test.

[0215] The comprehensive tester 2 is further used to parse the second RSRP in the read-back signal, and send the first RSRP value and the second RSRP value to the control device 1 .

[0217] In another implementation, the comprehensive tester 2 is further used to send the second RSRP value to the control device 1. The control device 1 is also used to determine the maximum second RSRP value from the second RSRP value when the antenna A1 is located at the initial angle and the second RSRP value received each time the antenna A1 rotates, because the insertion loss corresponding to the maximum second RSRP value is the minimum insertion loss of the downlink through the antenna A1, and thus, the antenna A1 angle corresponding to the maximum second RSRP value is the target elevation angle of the antenna A1.

[0218] Optionally, the control device 1 is used to control the switch module S0 to switch to the second connection mode, adjust the gain of the variable gain amplifier P0 to a preset value, and control the switch module S1 to switch to the third connection mode before sending the first instruction to the comprehensive tester 2. Specifically, the control device 1 is used to control the switch S1-1 and the switch S1-2 to be disconnected, and control the switch S1-3 and the switch S1-4 to be connected, that is, to switch to the third connection mode, so that in the third connection mode, the comprehensive tester 2 transmits the first signal with the first RSRP value through the antenna 1. The control device 1 is used to control the switch S0-1 and the switch S0-2 to be connected, and control the switch S0-3 and the switch S0-4 to be disconnected, that is, to control the switch module S0 to switch to the second connection mode, so that in the second connection mode, the comprehensive tester 2 receives the readback signal of the first signal from the device under test 5 through the antenna A0.

[0219] Compensate for the insertion loss of the downlink through antenna A1:

[0220] The control device 1 is also used to send a first rotation instruction to the motor M0 after finding the target azimuth angle of the antenna A1, and the instruction is used to instruct the motor M0 to rotate the antenna A1 to the target azimuth angle. The control device 1 is also used to send a second rotation instruction to the motor M1 after finding the target elevation angle of the antenna A1, and the instruction is used to instruct the motor M1 to rotate the antenna A1 to the target elevation angle. At this time, the insertion loss of the downlink through the antenna A1 is the smallest, and it can be considered that the maximum radiation direction of the antenna A1 is aligned with the receiving antenna of the device under test 5.

[0221] The control device 1 is also used to adjust the gain of the variable gain amplifier P1 based on the minimum insertion loss of the downlink through the antenna A1, specifically adjust the programmable attenuator in the variable gain amplifier P1 so that the adjusted insertion loss of the downlink through the antenna A1 is 0.

[0222] Compensate for the insertion loss of the uplink through antenna A0:

[0223] The control device 1 is also used to send a second instruction to the comprehensive tester 2 after finding the target azimuth angle and target elevation angle of the antenna A1. The second instruction is used to instruct the comprehensive tester 2 to receive a second signal from the device under test 5 through the antenna A0.

[0224] The comprehensive tester 2 is further configured to respond to the second instruction and receive the second signal from the device under test 5 via the antenna A0.

[0225] The comprehensive tester 2 is further used to send the measured power value of the second signal to the control device 1 .

[0226] The control device 1 is further configured to calculate the insertion loss of the uplink through the antenna A0 based on the difference between the target power value and the measured power value of the second signal.

[0227] The control device 1 is also used to adjust the gain of the variable gain amplifier P0 based on the insertion loss of the uplink through the antenna A0, specifically to adjust the programmable attenuator in the variable gain amplifier P0, so that the insertion loss of the uplink through the antenna A0 is 0 after adjustment.

[0228] In some embodiments, the control device 1 is also used to find the target angle (i.e., the target azimuth and target elevation) of the antenna A1 before measuring the RF index, so that the insertion loss of the downlink through the antenna A1 is minimized, and then the gain of the variable gain amplifier P1 is controlled based on the insertion loss of the antenna A1 at the target angle (i.e., the minimum insertion loss) to compensate for the insertion loss of the downlink. The control device 1 is also used to calculate the insertion loss of the uplink through the antenna A0 when the antenna A1 is at the target azimuth, and then the gain of the variable gain amplifier P0 is controlled based on the insertion loss of the uplink to compensate for the insertion loss of the uplink. The control device 1 is also used to measure the RF index of the device under test 5 when the antenna A1 is at the target angle (i.e., the target azimuth and target elevation) and the insertion loss is compensated.

[0229] In some embodiments, the control device 1 is used to find the target elevation angles of the antennas A2-A4 before measuring the physical layer rate, that is, to find the target elevation angle of antenna A2 when the insertion loss of the downlink through antenna A2 is minimized, to find the target elevation angle of antenna A3 when the insertion loss of the downlink through antenna A3 is minimized, and to find the target elevation angle of antenna A4 when the insertion loss of the downlink through antenna A4 is minimized, and then, based on the corresponding minimum insertion losses, the gains of the variable gain amplifiers P2-P4 are controlled to compensate for the insertion loss. Then, when the antennas A1-A4 are respectively located at their corresponding target elevation angles. Thus, when the antennas A1-A4 are respectively located at the corresponding target elevation angles, the physical layer rate is measured when the antennas A1-A4 are respectively connected to the comprehensive tester 2 through the variable gain amplifiers P1-P4 after the insertion loss is compensated. Optionally, at this time, the azimuths of the antennas A1-A4 can all be the target azimuths.

[0230] Among them, the target elevation angle of antenna A2 when the insertion loss of the downlink through antenna A2 is minimized, the target elevation angle of antenna A3 when the insertion loss of the downlink through antenna A3 is minimized, and the target elevation angle of antenna A4 when the insertion loss of the downlink through antenna A4 is minimized are all the same as the above-mentioned target elevation angle of antenna A1 when the insertion loss of the downlink through antenna A1 is minimized, and they are not repeated here.
